Abstract
An initial figure mask estimation of an image is generated using a figure ground segmentation system, thereby initially assigning each pixel in the image with a first attribute value or a second attribute value. A JigCut region segmentation of the image is generated. The figure mask estimation is processed with the JigCut region segmentation by (i) classifying the pixels of the image in each respective JigCut region in the JigCut region segmentation with the first attribute value when a predetermined number or a predetermined percentage of the pixels within the respective JigCut region have been initially assigned the first attribute value by the initial figure mask estimation and (ii) classifying the pixels of the image in each respective JigCut region in the JigCut region segmentation with the second attribute value otherwise.
